Probably nearly allied to Zela, de Niceville, but the secondary 

 sexual characters are entirely different. To compare the two genera 

 effectually, the females of both the type species are required. The 

 secondary sexual characters of the hindwing described above are 

 probably unique. The bowed-out inner margin of the forewing with 

 the same portion on the underside highly polished is doubtless also a 

 male characteristic. 

 45. ZAMPA ZENON, n. sp., PI. Q, Fig. 58, $. 

 Habitat : Pulo Laut, Borneo. 

 Expanse : $, 1*8 inches. 



Description : Male. Upperside, both wings shining dark ochreous- 

 brown. Forewing with an oval hyaline white spot at the base of the 

 second median interspace, a similar comma-shaped spot a little ob- 

 liquely inwardly below the first spot in the first median interspace, the 

 convexity of the spot directed to the base of the wing. Cilia cinereous. 

 Hindwing unmarked ; the sexual tuft of long recumbent hairs in the 

 middle of the wing inconspicuous and concolorous with the wing. 

 Cilia anteriorly narrow, cinereous, posteriorly becoming much longer 

 and orange-coloured. Underside, both wings have the ground-colour 

 paler than on the upperside. Forewing has the apex and outer margin 

 broadly paler, this pale area dying away to nothing towards the anal 

 angle of the wing ; the inner margin as far as the median nervure 

 and first median nervule pale and highly polished ; the disco-cellular 

 nervules defined by a narrow pale line ; the two hyaline spots as on 

 the upperside. Hindwing has the disco-cellular nervules defined by 

 a narrow pale line as on the forewing ; otherwise unmarked. 



In general appearance this species resembles Z. zeus, de Niceville, 

 described above, but has only two instead of three or four spots on the 

 forewing. On the underside of the forewing the present species has 

 a broad outer pale fascia, which is not found in Z. zeus. 



Described from a single example in Mr. H. J. Elwes' collection 

 captured in June, 1891, by Mr. W. Doherty.
